The angle of refraction of light ray in the corn oil is 20°.
Angle of refraction is the angle the refracted light ray makes with the normal to the oil-air interface.
Given data:
Angle of incidence = 30°
Analysis:
The refractive index of oil is 1.47.
Using the formula for refractive index(n) =
1.47 =
1.47(sin r) = sin 30
sin r =
sin r = 0.3401
r = arc sin(0.3401)
r = 19.88° which is approximately 20°

d. Jupiter E. Mercury F. Neptune
Answer:
Explanation:
Terrestrial planets are defined as planets which are formed by silicate. An important characteristic is that these planets have a solid surface. On the other hand, there are gaseous planets, which are bigger and more separated of the Sun.
In our Solar system, there are 4 terrestrial planets, which are Mercury, Venus, Earth, and Mars. Notice that they are the inner planets of the system.
So, in this case, the right chice is a. Mars, b. Earth and c. Venus. All three are terrestrial planets, that is, they have a rock solid surface.

Answer:
1.00 gram per milliliter (1 g/mL). In other words, 1 milliliter of water has a mass of 1 gram. A drop of water is 0.05 mL of water, so its mass would be 0.05 grams.
